Answer: 30%
Step-by-step explanation:
Given: Cupcakes have sprinkles = 15
Cupcakes didn't have sprinkles = 35
Total cupcakes = 15+35 = 50
The percentage of the cupcakes had sprinkles = [tex]\dfrac{\text{Cupcakes have sprinkles}}{\text{Total cupcakes}}\times100[/tex]
[tex]=\dfrac{15}{50}\times100\\\\= 30\%[/tex]
Hence, the percentage of the cupcakes had sprinkles = 30%
